Subject: [dpdk-dev] [PATCH v3 0/3] Fix Vhost regressions
Date: Wed, 29 Jul 2020 11:19:57 +0200 [thread overview]
Message-ID: <20200729092000.233036-1-maxime.coquelin@redhat.com> (raw)
This series aims at fixing the regressions reported by Intel QE.
I managed to reproduce the issues, and this series fixes them.
The two first patches fix the performance regression. They have
been tested by intel QE which confirms the fix.
In this v3, only change is in the third patch, which aims at
avoiding race by assuming the application is not modifying
the rte_epoll_event once it has requested the enablement of the
corresponding interrupt. I tested this v3 with l3fwd-power
example.
Thanks to Intel QE team for all the validation work!
Maxime
